Guidelines for the Assessment of Uncertainty for Hydrometric Measurement
In view of the increasing pressure on water resources, National Hydrological Services (NHSs) worldwide are faced with the challenge to deliver hydrological services of high quality, timeliness and proven credibility, to assist the decision making process of water and natural resources managers. Nowadays, it is commonly expected that these services must be based on information that includes an accurate assessment of its uncertainty. Stream discharge, the basic hydrological variable, is no exception, yet most measurements are still reported as a value without any information on its associated un ...

Интервью: Владимир Рябинин, Исполнительный секретарь Межправительственной океанографической комиссии (МОК) ЮНЕСКО
Бюллетень, Том 64(2). BMO, 2016Владимир Рябинин, Российская Федерация, 1 марта 2015 г. был назначен новым Исполнительным секре- тарем Межправительственной океанографической комиссии (МОК) ЮНЕСКО, что соответствует уровню помощника Генерального директора (ПГД) ЮНЕСКО. Г-н Рябинин перешел на работу в МОК из ВМО, где он с 2001 по 2015 г. занимал пост старшего научного сотрудника Всемирной программы исследований кли- мата (ВПИК). Годы, проведенные в ВМО, безусловно, окажут благотворное воздействие на тесное сотрудни- чество между двумя организациями. Бюллетень ВМО с удовольствием представляет г-на Рябинина читателям и предлагае ...

Plaidoyer en faveur de la prévision hydrologique à échéance prolongée pour une meilleure gestion des ressources en eau
L’eau douce est une ressource importante pour la vie humaine, l’activité économique, la santé des écosystèmes et les processus géophysiques. Au cours de la première décennie du XXIe siècle, l’Australie a subi des épisodes de conditions météorologiques extrêmes et vécu, en 2013, l’année la plus chaude jamais observée depuis le début des relevés, en 1910. Les conditions hydrologiques en Australie comptent parmi les plus variables du monde. Le pays peut traverser de longues périodes de sécheresse comme la «sécheresse du millénaire» qui a frappé, entre 1997 et 2000, la plus grande partie de l’est ...

L’entreprise hydrométéorologique: avantages des partenariats
L’OMM et le Service météorologique national (NWS) de l’Administration américaine pour les océans et l’atmosphère (NOAA) ont une fois encore organisé une réunion internationale en marge de la 95e assemblée annuelle de la Société météorologique américaine (AMS), en janvier. Cette réunion a été l’occasion d’examiner le rôle important et unique joué par les Services météorologiques et hydrologiques nationaux (SMHN) pour aider la société à prendre des décisions plus judicieuses pour faire face à la vulnérabilité croissante de l’environnement aux phénomènes météorologiques et climatiques extrêmes.

Progrès réalisés dans l’observation et la prévision du phénomène ENSO
Bulletin, Vol. 64(1). OMM, 2016Les gouvernements, les entreprises du secteur privé et les particuliers sont de plus en plus exigeants lorsqu’il s’agit de la qualité des services climatologiques, d’où l’importance du Cadre mondial pour les services climatologiques (CMSC). Cependant, certaines composantes du réseau d’observation de l’océan – pourtant essentielles à la prestation de ces services – risquent de se dégrader, et les systèmes de prévision climatique ont du mal à rester au fait des attentes croissantes quant à l’exactitude et à la fi abilité des services.1234
GCOS, 201. Report of the Nineteenth Session of the Ocean Observations Panel for Climate (OOPC-19)
A large focus of the meeting was completing the GCOS Implementation Plan, in addition to progressing activities in the OOPC Work Plan. The first day of the meeting was held jointly with the JCOMM Observations Coordination Group, and hence was focused on discussing the structure and focus of the ocean section of the GCOS IP, and refining the network based actions for the plan. The Second day was focused on further refining the package of Essential Ocean Variable Specification Sheets, particularly ensuring consistent articulation of applications areas, and phenomena to capture. The 3rd Day focus ...
Communicating Climate Change Scenarios With Decision Makers: Lecture by Dr. Holly Hartmann, Research Hydrologist
In this 1-hour lecture, presented in three parts, research hydrologist Dr. Holly Hartmann discusses issues and approaches for communicating with decision-makers regarding climate change topics in water management and planning. Dr. Hartmann is a national leader in research related to the development of decision support tools for climate, water, and other resource management applications, especially linking research with the needs of decision-makers and moving research into agency operations. Dr. Hartmann is Carpe Diem West’s Director of Climate Science Applications. Previously she was Director ...
Climate and Water Resources Management, Part 1: Climate Variability and Change
Climate is changing at unprecedented rates in recorded history. A variety of lines of evidence demonstrate that climate change is likely to affect the hydrologic cycle and thus create new challenges in water management. This requires that climate change information be included in water and water-related resources planning, operations, and management. Climate and Water Resources Management, Part 1: Climate Variability and Change describes the terminology, global evidence, regional manifestations, and basic science of global climate variability and anthropogenic change, with a focus on water res ...
Real-time Storm Surge Products
This lesson will describe the real-time storm surge products that are issued by the National Hurricane Center (NHC) and National Weather Service Weather Forecast Offices (NWS WFOs) during a significant tropical cyclone event along the Atlantic and Gulf coasts of the United States. Tropical cyclones that threaten a coastline have the potential to inflict devastating damage to communities. Real-time storm surge information will assist decision-makers in their plans and preparation work for these events. Basic familiarity with probabilistic forecast guidance is required. It is recommended that us ...
Forecasters' Overview of the Mediterranean and Europe
This module provides an introduction to the European continent and the Mediterranean and Black Sea areas for weather forecasters. It focuses on geography, climatology, oceanography, major aspects of the synoptic and mesoscale weather patterns, and hazards to aviation and maritime operations. Geography covers major political boundaries, cities, ports, topographical features, rivers, and volcanic areas. Climatology covers the seasonal climatology of jet stream, synoptic weather systems, extratropical cyclones, and high winds and seas. Oceanography includes major bathymetric features; mean sea su ...

TsunamiReady: Guidelines for Mitigation, Preparedness, and Response
The TsunamiReady® program began in 2001 to promote tsunami hazard preparedness and improve public safety before, during, and after tsunami emergencies. In 2015, the National Weather Service updated the TsunamiReady Guidelines based directly on emergency management principles and with input from the social sciences. This training provides an overview of the 2015 guidelines, which are focused on mitigation, preparedness, and response. The training will equip community officials and others interested in becoming TsunamiReady with strategies for streamlining their implementation of the guidelines. ...
Sea Level Change: Datums and Terminology
This lesson addresses how sea level is determined and applied. It starts with a general discussion of the surfaces that form the basis of measurement, called datums, then looks more closely at the vertical datums that form the basis of height measurements. We cover tidal datums in more depth, including the different datums, their extent, period of record (called a tidal epoch), and common applications. We conclude with a look at some data resources for tidal datums and sea level trends.
